Abstract: A medical device includes a handle having a first end and a second end, a mixer positioned within the handle and an adapter coupled to the second end of the handle. A delivery needle includes a distal end, a proximal end, and a lumen extending from the distal end to the proximal end. The proximal end of the delivery needle is coupled to the first end of the handle. A sensor cable includes a distal end and a proximal end, and the proximal end of the sensor cable is positioned within the handle, and the distal end extends distally through the lumen of the delivery needle.

Abstract: An example medical device includes a handle, an actuation mechanism coupled to the handle, and a delivery needle, wherein a proximal end of the delivery needle is coupled to a first end of the handle. A fluid delivery device is coupled to a second end of the housing, and a retractable sensor is positioned within the handle. The retractable sensor is configured to extend distally through a lumen of the delivery needle in a non-retracted position during placement of the delivery needle within a body of a patient, wherein actuation of the actuation mechanism causes the retractable sensor to retract proximally through the lumen of the delivery needle into the handle to a retracted position.
